Minimal Lorentz Surfaces in Pseudo-Euclidean 4-Space with Neutral Metric
Yana Aleksieva, Velichka Milousheva
We study minimal Lorentz surfaces in the pseudo-Euclidean 4-space with neutral metric whose first normal space is two-dimensional and whose Gauss curvature and normal curvature…
General Rotational Surfaces in Pseudo-Euclidean 4-Space with Neutral Metric
Yana Aleksieva, Velichka Milousheva, Nurettin Cenk Turgay
We define general rotational surfaces of elliptic and hyperbolic type in the pseudo-Euclidean 4-space with neutral metric which are analogous to the general rotational surfaces of…
Rotational Surfaces with Constant Mean Curvature in Pseudo-Euclidean 4-Space with Neutral Metric
Yana Aleksieva, Velichka Milousheva
We give the classification of constant mean curvature rotational surfaces of elliptic, hyperbolic, and parabolic type in the four-dimensional pseudo-Euclidean space with neutral me…
On the Theory of Lorentz Surfaces with Parallel Normalized Mean Curvature Vector Field in Pseudo-Euclidean 4-Space
Yana Aleksieva, Georgi Ganchev, Velichka Milousheva
We develop an invariant local theory of Lorentz surfaces in pseudo-Euclidean 4-space by use of a linear map of Weingarten type. We find a geometrically determined moving frame fiel…
